The current state of knowledge of the
chronology of the ancients is wholly unsatisfactory and is
inconsistent with known facts. There are several pointers to
constructing a correct chronology.

1. The drying up of the Saraswati river
by 1900 BCE. This is incontrovertible evidence that must be
accounted for. It is a river in full majesty flowing from the
mountains to the sea as described in the RgVeda.

2. The dating of Chandragupta Maurya by
Sir William Jones to 312 BCE is problematical for several
reasons which we will discuss.

3.The ending of the Mahabharata War to
the beginning of Kaliyuga (3139 BCE)

4. The credibility of Megasthenes'
writings, since his original manuscript appears to have
been lost

Some key dates for which there is
evidentiary material attesting the dates mentioned below.

Some questions to ponder as we
contemplate this chronology, posted by poster ashyam in IF

If the above
are true it has so much significance since
it is not the way we learnt history and
should turn around the way we see things.
Before taking this point to public I would
like to debate/discuss about it and validate
against the material evidences we have.
People who know it better, please
contribute.

1. Buddha is said to have lived in 1800s BC
- Are there any evidence that Buddhism was
practiced in India around 1500BC?
- There are many museums in India, China,
Nepal and Sri Lanka which suposed to have
have many relics of Buddha, like tooth,
nail, hair etc. Did anybody say that they
date back to the era Buddha lived?

2. Maurya Empire in 1500BC
- I don't think it disputes Chanakya was a
contemporary of Chandragupta Maurya. During
Chanakya's time Takshashila and Nalanda
Universities were very prominent. If so, do
the stones and other materials we get from
Nalanda and Takshashila date back to more
than 1500BC?
- Ashoka was the grandson of Chandragupta
Maurya. When he spread Buddhism all across
globe, are there any evidence that Buddhism
was practiced in Central Asia and China
around 1000BC?
- Ashoka built Sanchi Stupa at Saranath.
Does radio carbon dating of materials there
date back to 1500BC?

3. Gupta Empire in 300BC
- If Gupta empire was in 300BC, what is the
Gupta empire that we know as current Gupta
empire?

4. Shankaracharya in 500BC
- I read many times that Kanchi Mutt was
2500 years old and I never understood how.
If Shankaracharya lived in 500BC, that would
explain.
- Shankaracharya's mission was to bring back
vedic way of life
- Then Buddhism's decline must have started
around that time
- But we still had Buddhist empires after
this period.

Do we have evidence for the above? How did
people prove the post Kaushal made.

Niraj Mohanka's
Royal chronologyA good first attempt has been made by
Niraj Mohanka .
There are several dates yet to be resolved in a
satisfactory manner and it does not conform to the above dates.
